Real output

A shortened row read on 23 October 2026 during owner-account acceptance testing. Results change as the corpus changes.

    "username": "forrentdubai",
    "title": "For Rent in Dubai; Аренда недвижимости",

The dataset contains the delivered rows. The run's OUTPUT record adds counts, an explicit outcome (results, valid_zero_result, limited or incomplete), source timings and any stop reason. A source failure fails the run; it is never presented as a successful empty search.

Cost

$0.005 per run start + $0.005 per group delivered. With the 256 MB memory limit there is one start event. Ten billable results cost about $0.055 in Actor fees. Zero matches incur only the start fee. Prices and any platform charges shown by Apify at launch are authoritative.

Set Maximum charge per run before starting (default $0.50). Delivery stops when the remaining budget cannot pay for another result; duplicate results are not billed twice in a run. Apify free-plan accounts receive at most 50 billable results per run. The amount of data in a snapshot may be larger than your budget permits.

Freshness and interpretation

Results come from an existing catalog, not a live Telegram check. Use each audience or signal measurement timestamp. Some observations can be weeks old; null means unmeasured. Coverage and matches vary by topic and language.

Semantic matches may include adjacent topics. Use mustInclude to pin a place or phrase; strict matching narrows results. requestLikeSignals30d is a heuristic activity signal, not verified buyers or unique people. Null means unmeasured. Empty topics produce an actionable input error.

Why use it

Search by meaning across languages, then compare catalog audience and activity in one table.

This Actor reads public catalog data. It does not join groups, send messages or contact anyone. Verify the source and suitability before outreach or business decisions.

API and scheduled runs

Use the same JSON input with the public Actor API. Keep your Apify token in an environment variable.

curl -X POST \
  -H "Authorization: Bearer $APIFY_TOKEN" \
  -H "Content-Type: application/json" \
  --data @input.json \
  "https://api.apify.com/v2/acts/telegrambest~telegram-group-discovery/run-sync-get-dataset-items?memory=256&timeout=180&maxTotalChargeUsd=0.50"

For longer runs use Apify's asynchronous run endpoint and fetch the dataset after completion. Where available, onlyNew=true remembers delivered items for this Actor and your account so scheduled searches skip them. Keep it off when you want a full repeatable snapshot.
